MLB's replay system was designed to mitigate the human element in umpiring decisions. Instead, the human element is surfacing in a different form, Red Sox manager John Farrell said Sunday night.

"It's hard to have any faith in the system,'' Farrell said after Boston's 3-2 loss to the Yankees.

Farrell became the first manager to be ejected for disputing a play that was reviewed on replay after umpires reversed their call on what would have been an inning-ending double play in the fourth inning. Once the call was reversed, the Yankees were credited with a run that would not have counted had the original call stood.

That run ultimately proved to be the margin of victory for the Yankees.
